Prasarana says that it has been analysing and carrying out rectification work on the suspended LRT Kelana Jaya Line by changing the power supply modem device in the automatic train control (ATC) system, and anticipates that the the service will be operational soon, The Edge reports.
Its president and group CEO Mohd Azharuddin Mat Sah said troubleshooting work has been ongoing since Wednesday night (November 9), the day Rapid KL announced that 16 stations along the Line would be closed for seven days until November 15, to facilitate repair works.
He said that the company had carried out movement tests on 10 LRT trains, and found that one train had to be controlled manually, but after several tests, it ran smoothly. “It is a positive sign for the LRT train service to return to operation in the near future,” he told reporters at a press conference yesterday.
He said that that the arrival of experts from Canadian OEM supplier Thales Group will assist in dealing with the issue, but added that the company will conduct more tests before the Line is restarted. “We hope that with the help of Thales experts and engineers, we can speed up the ATC system restoration process,” he said.
The Star reported that Rapid Rail had identified that the problem was due to an unstable ATC, which aside from disrupting the service prior to the halt in operations, also caused some trains to “disappear” intermittently from the monitoring screen of the LRT operation and control centre, posing a huge hazard,
The decision to pull the plug for a week was made after taking into account passenger safety as well as the time it would take to identify the cause of the problem. “The trains were unable to move automatically, which indicated a problem. We could not see the trains on our screens, and that is very important for us,” he said.
“As an accountable organisation, we had to make the very tough call to suspend operations (for a week). We acknowledge it has greatly inconvenienced many, but we certainly do not want any recurrence of May 2021’s incident (where two trains, one driven manually, collided head-on in the tunnel between Kampung Baru and KLCC),” he explained.

David Copperfield must be astonished with Malaysia. After LCS vanished now we got train vanished also. Kita boleh!
Your Excellency Mr Sim
Can we request David Copperfield or our local shaman to “vanish” Weewee n Co,and those top brass of our shithole LRT ?
Better still we VOTE THEM OUT.
Agreed. We need David Copperfield to ‘vanish’ Loke & Co, and all their fellows sewaktu dengannya. 22months oredy enough damaging 20 years reputation of near flawless operation.
Used to vote for BN. But no more for me. With new party, also not going vote for PN. Reasons: corruption, traitors, incompetence and talking nonsense
Same. Same. Better vote out this Wee
Funny to see many high self voting from PH cybertroopers are condemning comments about BN and PN. While PH cybertroopers usual, also lying that about manifesto promises when they become gomen, also lies to the public
@Spin Too Much
Because you are just low mentality guy. There is no other cybetroopers condemning comments about PH, except BN and PN cyber troopers are doing high self voting and condemning comments about PH while BN and PN cybertroopers usual also lying to the public on others and also manifesto promises
How and when did a LCS vanished? A whole ship? Really?
6 of them
Someone has not been doing preventive maintenance…
How do you propose to do preventive maintenance on software?
typically it would be checking on the firmware on patch management. software, OS, even the hardware hosting the software could have maintenance to be done too.
Either way, since the incident has happened, need to know the root cause analysis report to detetmine is it because of negligence for not conducting preventive maintenance or something else that will need to be considered to include in future preventive maintenance.
Well done. Problem caused by system error but Rapid has rapidly found the problem and worked out a solution. Hope the experts can tell why their system had failed.
People, drop the political shenanigan and let’s get back to moving again.
The system from Thales signaling sytem is getting aging , and MAY BE vulnerable for any cyber attack if doesn’t protect well and may be will cripple the whole line of operation, this is something that they need to look into. Also, rolling stock for KLAV currently , especially spare parts upgrade , maintenance and overhaul is needed the most, we rely too much from the OEM supplier but localization is building bit by bit but still not obvious in results, this is what they need to take note on. Kelana Jaya Line is at their bottleneck of the operation , they need something extra.
ATC, as a safety related system, is usually not connected to the internet. Therefore it should be safe from ‘cyber attacks’. If it would be prone to cyber attacks, not only the operation would be affected, but passengers lives too.
All systems are networked. Even if the key system is not connected to the internet, some connected portals could be linked to external network for remote troubleshooting.
I guess they should have called you instead of staff from the Canadian manufacturer? As you seem to know everything about safety- related, hard-realtime ATC networking, it should be easy for you to find the cause for the malfunction.
Brader don’t be stupid. Even nuclear power plant highly secured control computers had been hacked before. In all probability the system error is due to programming glitch rather than a hacker but we cannot ignore that possibility.
Nuclear power plants don’t use software at all, they are hard-wired. That’s worldwide industry standard.
Not a single time a nuclear power plant was hacked (possibly in 4th class trash movies they were).
Don’t use software at all? Brader stop watching Simpsons thinking a nuclear plant is dependent on a yellow coloured buffoon to toggle switches and dials. Everything complex runs on software nowadays.
If trains “disappear” from the screen,high time top executives should also ‘disappear ” from Prasarana.
Has any one been sacked from the serious 2 train collision last year? None at all,as expected.Only the Tajuddin dude was sacked for uncouth press relations.
As GLCs,they r funded by tax Ringgit.Without our taxes,not a single train can be bought.
The new regime garmen hopefully,will put an end to these shit.Now Weewee just do some “keluarga damage control” press relations to placate the growing anger.Nonetheless,the shit remains in this money pit LRT.
I also hope David Copperfield can make you ‘vanish’ along with Loke & Co and sewaktu dengannya.
Wee is doing worst duty job ever than Loke & Co.
And what did Loke & Co do well other than collecting money from sales of fancy plates? Oh right the moronic act of legalising super dark tints that is a hazard to other road users. Dr Wee showed he is far more sane than that.
So what Dr Wee do well? Dr Wee have lost their promises after making good promises to the public during BN-PN era. Repair so fast about LRT also whether can work properly or not. Complaining so much about Loke & Co because you are low mentality and didn’t know Loke & Co can do better than Dr Wee
at least the trains didn’t break down during anthony loke era.
No your right. Its just the monorail line did not work under him thats all. Oh you mean that wasnt his fault, but this lrt breakdown somehow is Dr Wee fault? Nice logic there.
haih…if only we could see some politicians ‘disappearing’ from the ‘scene’
Yup. This one

Rome was not built in lone day. Likewise the happenings at LRT kelana line.
Should breakdown of this magnitude ever happen in Japan, or to in Singapore , I guess heads will roll.
Malaysia has been plagued by culture of low accountability. Mishaps, failure, manipulation related to this shortcoming are many, just a few examples ,1mdb, LCA ship, cow rearing project.
These happened as the country is run based on preference culture. Some are fortunate to enjoy benefits all along the way, from schooling to employment. At the end, those who are less capable were put on to take charge of key positions, this brings string of issues.
LRT maintenance could be not up to par, quick fixes applied along the way, eventually those little things accumulated to a major one.
Yet today, I read prasana wantonly pushed the responsibility away, pointing the finger at bombardier, claiming it is a manufacturer fault. Can this be the case after do many years of using the train?
When technical glitch is being blamed upon the government of the day, it shows how stupid are Malaysians or how penetrative are the so called political “Red Bean Armies”. It (glitches)
had happened in Sgpore MRT before, which is touted as the best MRT system in the world, by some.
